A should be B because the other option don’t make sense and part B I got 4 11/12
If you factor it then your answer will be -3(-3z-5) if you simplify the answer is 9z+15
They want to make a total of $1200.
55*10=550
55*8=440
440-550=990
1200-990=210
210/35=6
So they should sell the other plants for $6 each.

Solution:
Given expression is
.
To simplify the expression 
Let us first convert the mixed fraction into improper fraction.



Take LCM for the denominators (LCM of 4, 8 = 8) and make the same.



Now, divide 51 by 8 and again write it in the mixed fraction.


Hence, the simplified answer is
.
The pattern:
So it goes, 1, 2, 3, as the first number in each equation right.
Then it goes 4,5,6 as the second number in each equation.
<span>In other words, the first number + 3 = the second number
</span>
The sum or 3rd number is a zig zag pattern from the first and second numbers as shown below.
1 2 3 4 5 6 <span>7 </span>8 9
4 <span>5 </span>6 7 8 9 10 11 <span>12
</span>
1 * 5 = 5, 2 * 6 = 12, 3 * 7 = 21 .... 8 * 12 = 96
<span>So the answer of </span><span>8+11=96</span>
